In order to avoid the problem that the ball produced by the conventional method avoids the risk of the battery 15 in the high-temperature vulcanization process, the elastic force at the position where the battery 15 is installed is weak, and the ball for providing the overall elastic force is normal for the ball. As shown in FIGS. 1 and 2, the apparatus for mounting the circuit module 13 and the battery 15 includes an inner casing 12, a mounting chamber 11, and a connecting portion 10, and the circuit module 13 is fixedly mounted in the inner casing 12 for The circuit module 13 is prevented from vibrating or dislodging in the inner casing 12, causing damage or data acquisition error. The inner casing 12 is provided with a limited position slot, and the circuit module 13 is limitedly installed in the limiting slot. The circuit module 13 is closely matched with the limiting slot to ensure the stability of the circuit module 13 in the inner casing 12.
